Just wanted to share a scenario/solution.
If you use the Prometheus Chart in a protected subfolder in you web application. (protected by a web.config and roles enabled), you also have to allow the members to access chartimage.axd.
| <location path="chartimage.axd"> |
| <system.web> |
| <authorization> |
| <allow roles="K2WFVendorAdmin" /> |
| </authorization> |
| </system.web> |
| </location> |
Otherwise you get prompted to enter your username and password.
Regards,
Nicolas
